Menene matsi a tsarin birki na motar?
Menene matsi a cikin birki na hydraulic na motocin fasinja?
Da farko, yana da ma'ana don fahimtar irin waɗannan ra'ayoyi kamar matsa lamba a cikin tsarin na'ura mai aiki da karfin ruwa da kuma matsin lamba ta hanyar calipers ko sandunan silinda kai tsaye a kan ƙusoshin birki.
Matsalolin da ke cikin tsarin na'ura mai aiki da karfin ruwa na motar kanta a cikin dukkan sassanta kusan iri ɗaya ne kuma a cikin mafi girman motocin zamani kusan mashaya 180 (idan kun ƙidaya a cikin yanayi, to wannan shine kusan 177 ATM). A cikin wasanni ko motocin da ake cajin farar hula, wannan matsa lamba na iya kaiwa mashaya 200.
Tabbas, ba shi yiwuwa a haifar da irin wannan matsa lamba kai tsaye kawai ta ƙoƙarin ƙarfin tsokar mutum. Saboda haka, akwai abubuwa biyu masu ƙarfafawa a tsarin birki na mota.
- Lever mai feda. Saboda lever, wanda aka ba da shi ta hanyar zane na taron pedal, matsa lamba akan feda da farko da direba ya yi amfani da shi yana ƙaruwa sau 4-8, dangane da alamar mota.
- injin kara kuzari. Wannan taron kuma yana ƙara matsa lamba akan babban silinda na birki da kusan sau 2. Kodayake ƙira daban-daban na wannan rukunin suna ba da babban bambanci sosai a cikin ƙarin ƙarfi a cikin tsarin.
A haƙiƙa, matsa lamba na aiki a cikin tsarin birki yayin aiki na yau da kullun na mota da wuya ya wuce yanayi 100. Kuma kawai a lokacin birki na gaggawa, mutumin da ya ci gaba da kyau yana iya danna ƙafar ƙafa a kan feda don haifar da matsa lamba a cikin tsarin sama da yanayi 100, amma wannan yana faruwa ne kawai a lokuta na musamman.
Matsi na piston caliper ko silinda masu aiki akan pads ya bambanta da matsa lamba na hydraulic a cikin tsarin birki. Anan ƙa'idar tayi kama da ƙa'idar aiki na latsawa na'ura mai aiki da karfin ruwa, inda karamin sashe famfo Silinda ke yin famfo ruwa a cikin silinda na wani yanki mafi girma. Ana ƙididdige karuwar ƙarfin ƙarfi a matsayin rabon diamita na Silinda. Idan ka kula da fistan caliper birki na motar fasinja, zai kasance sau da yawa girma a diamita fiye da fistan babban silinda birki. Sabili da haka, matsa lamba akan pads da kansu za su karu saboda bambancin diamita na Silinda.
Matsin birki na iska
Ka'idar aiki na tsarin pneumatic ya ɗan bambanta da tsarin hydraulic. Na farko, matsa lamba akan pads an halicce su ta hanyar iska, ba matsa lamba na ruwa ba. Abu na biyu, direban baya haifar da matsa lamba tare da ƙarfin muscular na kafa. Iskar da ke cikin na'urar tana jujjuyawa ne ta hanyar kwampreso, wanda ke karɓar kuzari daga injin. Kuma direban, ta hanyar latsa birki, kawai yana buɗe bawul ɗin, wanda ke rarraba iska a kan manyan hanyoyi.
Bawul ɗin rarrabawa a cikin tsarin pneumatic yana sarrafa matsa lamba da aka aika zuwa ɗakunan birki. Saboda wannan, ana daidaita ƙarfin matsi na pads zuwa ganguna.
Matsakaicin matsa lamba a cikin layi na tsarin pneumatic yawanci baya wuce 10-12 yanayi. Wannan shine matsi wanda aka tsara mai karɓa don shi. Duk da haka, ƙarfin matsi na pads zuwa ganguna ya fi girma. Ƙarfafawa yana faruwa a cikin membrane (ƙananan sau da yawa - piston) ɗakunan pneumatic, wanda ya sanya matsa lamba akan pads.
Tsarin birki na huhu akan motar fasinja ba kasafai ba ne. Magungunan huhu sun fara bayyana gaɓoɓi akan motocin amfani ko ƙananan manyan motoci. Wani lokaci birki na pneumatic yana kwafin na'ura mai aiki da karfin ruwa, wato tsarin yana da da'irori daban-daban guda biyu, wanda ke dagula tsarin, amma yana ƙara amincin birki.
